DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

With reference to the drawings, and in particular to FIGS. 1 through 3, a beverage can cooling device 10 according to a first preferred embodiment of the invention will now be described. The device 10 includes a container 12 preferably formed from a transparent or translucent plastic material and connected to a supporting base 14 by a plurality of screws or other conventional fastening mechanism. The container 12 has an open upper end which may be selectively closed by a removable lid or cover 16 including a shoulder or lip 18 which engages the upper peripheral edge of the top opening in the container 12.

The base 14 is preferably molded from a plastic material and includes a substantially hollow interior closed by a floor plate 20. A recess 22 formed in the floor plate 20 receives a battery holder 24 secured therein by a battery cover plate 26 secured by cooperating latch members 28 on the cover plate 26 and 30 in the recess 22. A plurality of rubber non-skid feet 32 and 34 project downwardly from the floor plate 20 and support the device 10 on an upright surface such as a table top during use of the device 10. The floor plate 20 is secured to the base 14 by a plurality of screws (not shown) which extend through apertures 36 formed through the floor plate 20 and into engagement with threaded posts 38 molded into the base 14. The base 14 also includes a plurality of interior molded stiffening ribs 40 to add rigidity and strength.

An electric motor 42 including an attached gear reduction mechanism 44 mounted within the interior of the base 14 rotates a plurality of beverage container turntables 62 and 68 through a gear mechanism described in further detail hereinafter. A frictional lock ring 46 press fit around a main gear shaft 60 secures the shaft 60 for rotation with a rotary output shaft 45 of the motor gear reduction mechanism 44, mounting the main gear 58 for rotation by the motor 42. An 0-ring 61 provides a water tight seal for the shaft 60. A pair of bearings 54 and 56 press fit within complementary recesses 55 and 57 formed in an interior bottom portion of the container 12 support respective turntable shafts 69 and 63 for rotation. Driven gears 70 and 64 fixed for rotation with the respective shafts 69 and 63 engage the main gear 58, such that turntables 68 and 62 are driven in rotation when a user connects the motor 42 to a source of electricity, such as conventional batteries in holder 24, by engaging an on-off rocker switch 82 mounted in a console portion 80 of the base 14. The device 10 may be optionally provided with alternative battery and A/C power in a conventional manner.

The turntables 62 and 68 take the form of cylindrical receptacles which receive respective collets 72 and 74. The collets 72 and 74 may be press fit or glued within the turntables 62 and 68. The collets 72 and 74 include stepped diameter inner members 76 and 78 preferably formed from an elastomeric material such as rubber and provided with a plurality of axially extending circumferentially spaced ribs such that the collets elastically expand and contract to some extent, providing a firm frictional engagement with conventional beverage containers such as soda cans, beer cans, soda bottles, and wine bottles. A particularly preferred feature of the invention is the provision of a stepped diameter configuration to the collets, with a smaller diameter bottom portion 77, 79 and a larger diameter upper portion 76, 78 to allow frictional engagement with beverage containers of different sizes. While two different diameter steps are shown, it should be understood that more steps, such as three or four, or more, maybe be provided within the intended scope of the invention.

With reference to FIGS. 4 through 6, a manual hand crank driven embodiment of the invention 100 includes a container 102 having a lid or cover 104 selectively secured over an open top end of the container 102 by a latch 106. The container 102 includes an integral base 108 provided with a plurality of adhesive secured non-skid feet 110 adapted for supporting the device 100 on a surface such as a table or counter. A plurality of buttons 112 (only one shown) secured to the container 102 allow for detachable securement of a carrying strap or handle (not shown). A C-clip 116 engages a groove provided in a reduced diameter shaft portion of a crank handle 114 extending through an aperture 118 provided through a radially outer portion of dome shaped flywheel 120, securing the handle 114 to the flywheel 120. A C-clip 122 engaging a circumferential groove formed on an inner end of a central hollow cylindrical shaft 138 of the flywheel 120 extending through a central circular aperture 126 of the cover 120, mounting the flywheel for rotation relative to the lid 104 and container 102. A shallow cylindrical recess 124 formed centrally in the lid 104 receives the flywheel 120 for rotation therein.

A drive shaft 128 centrally disposed within the container 102 and extending axially therein includes a plurality of radially extending fins 129, 131, and 133 for the purpose of stirring a cooling medium such as an ice and water mixture filling the interior of the container 102. A downwardly opening square aperture 136 of the shaft 138 receives a reduced size square upper end portion 130 of the shaft 128, keying the shaft 128 for rotation with the flywheel 120.

In a similar manner, a reduced size square lower end portion 140 of the shaft 128 received within a square socket 142 connected to a main gear 144 keys the gear for rotation with the shaft 128. A mounting plate 146 includes four circular apertures 148, 150, 152, 154 for the purpose of rotatably mounting respective turntables 160, 164, 182, 178 therein. A central circular aperture 156 in the mounting plate 146 receives the drive socket 142 of the main gear 144 therethrough. A cylindrical stub shaft portion 145 of the main gear 144 received within a complementary recess 147 molded into the base 108 serves as a bearing, supporting the gear 144 for rotation. Each of the turntables 160, 164, 178, and 182 includes a driven gear engaging the main gear 144. FIG. 5 illustrates two of the four driven gears, 180 and 186.

Collets 162, 166, 180, and 184 secured for rotation with respective turntables 160, 164, 178, 182 preferably include a stepped diameter cylindrical construction and an expansible ribbed elastomeric construction, as described in detail in connection with the first embodiment 10.

In the manner of use of the device 100, a user positions one or more beverage containers within the collets 162, 166, 180, and 184, fills the interior of the container 102 with an ice and water mixture, replaces the lid 104, and rotates the crank handle 114 to rotate the beverage containers within the cooling medium, causing rapid cooling of the beverage containers and their contents.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
